FEEZD-WATEB REGULATGB-a Specification of Letters IPatent.:

Application-filedFebruary 13, 1915. Serial No. 7,928.

To all whom it may concern Be it known thatI, NlIOHAEL OWEN, a subject of the Kingv of England, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Feedater Regulators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a feed water regulator for boilers, and the primary ob ject of my invention is to provide positive and reliable means, in a manner as hereinafter set forth, for controlling the supply of-water to a boiler, the means employed including a float actuated mechanism for controlling the operation of a valve, and the mechanism is of such construction as to be very sensitive to a float movement and yet produce considerable leverage foractuating the value.

A further object of this invention is to provide a feed water regulator for boilers wherein a novel boiler connection is utilized for housing float actuated mechanism that controls the valve, and the connection is provided with means for limiting and adjusting movement of the mechanism.

In the general make-up of the feed water regulator, the parts are. constructed with a view of reducing the cost of manufacture and at the same time retain the features by which accuracy, safety, durability, simplicity and ease of assembling are secured, an with such ends in view, the invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.

Reference will now be had to the drawings, wherein- Figure 1 is a plan of the feed water regulator, partly broken away and partly in section, and Fig. 2 is a side elevation of the same, partly broken away and partly in section, illustrating its installation in connection with a boiler.

In the drawing, 1 denotes a water supply pipe extending into a boiler 2 and constituting a water feed therefor. This pipe is provided with ordinary shut off valves 3 and with a conventional form of check valve 4.

Connected to the pipe 1 are pipe connections 5 constituting a by-pass around one of the valves 3 and the by-pass pipe connection includes a ball check valve 6. The valvular member of this ball check valve is of a corn ventional form, but the stem, 7 thereofex; tends into a. bonnet 8 carried by the valve body.

Communicating with the top of the boiler- 2 is a tubular or hollow upright -whichghas the inner end thereof provided with an angle bracket 10 serving as a pivot for an end of a float rod 11. The float rod llhas a spherical hollow float 12 and said rod contiguous to the pivoted end thereof, is pivotally connected, as at 13, to the lower end of a reach rod 14: which extends upwardly through thetubular upright 9'.

lvliounted upon the uppercnd of the tubular upright 9 is a casing 15 having a reduced end 16 provided with a bearing 17 and a stuffing box 18 for a rock shaft 19. Mount: ed upon the rock shaft 19' within the casing 15 is a crank 20 and said crank is pivotally connected as at 21, to the upper end of the reach rod 1 1. The crank 20 is fixed to the rock shaft 19 through the medium of a set screw 22 or other fastening means and easy access is had to said fastening means through the medium of an opening 23 normally closed by a detachable screw plug 24.

The outer end of the rock shaft 19 is provided with a long crank 25 and said crank has the end thereof pivotally connected, as at 26 to a connecting rod 27, said rod having a turn buckle 28 whereby it can be increased or decreased in its longitudinal dimension. The connecting rod 27 is pivotally connected to a crank 29 upon the end of a crank shaft 30, journaled in the bonnet 8 of the valve 6, and said crank shaft has a crank 31 within the bonnet 8 adapted to impinge the valve stem 7 and close the check valve.

With the valve 8 closed, water can flow or be pumped through the by-pass pipe connections 5, to feed the boiler 2 until the float 12 actuates the leverage mechanism. When the water within the boiler 2 reaches a predetermined level, the float 12 actuates the leverage mechanism, which is susceptible to a very slight movement of the float 12, consequently the valve 6 is closed at an initial movement of the float 12 and remains closed until the level of water within the boiler is lowered.

Serving as a stop and means for limiting the upward movement of the crank 20 and Patented Jan; 2535 9154;

the reach rod "14 is a screw bolt 32 in a stuffing box 33, carried by the top of the casing 15.

I attach considerable importance to the shafts 19 and 30 and the cranks thereof, these shafts cooperating with the long float rod 11 in providing a mechanism for actuating the valve 6 which is very sensitive and is brought into operation by almost an imperceptible movement of the float.

- It is thought that the operation and utility of the water regulator will be apparent without further description, and while in the drawing there is illustrated a preferred embodiment of my invention, it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claims.

I What I claim is 1. In a feed Water regulator for boilers,

thecombination with a Water supply pipe provided with a base valve adapted to control the supply of water to a boiler, of a bonnet on said valve, a crank shaft journaled in said bonnet and having a crank adapted to close said ball valve, a crank on the outer end of said shaft, a hollow upright, adapted for communication with the boiler, a casing at the upper end of said upright, a reach rod extending through said nation with a boiler, a water supply pipetherefor, and a ball valve for controlling the supply of water to said boiler, "of an upright in communication with said boiler, an angle bracket on the lower end of said upright against the inner side of said boiler,

a casing carried by the upper end of said upright, a rock shaft supported by said casing, means actuated by amovement of said rock shaft adapted to close said ball valve, a reach rod extending through said upright for imparting movement to said rock shaft, and a float arm carried by said angle bracket above the'water in said boiler and adapted to raise and lower said reach rod. i
